# curl/libcurl CMake script
# by Tetetest and Sukender (Benoit Neil)
# TODO:
# The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
# Add full (4 or 5 libs) SSL support
# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).
# Check on all possible platforms
# Test with as many configurations possible (With or without any option)
# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
# - lists of headers that 'configure' checks for;
# - curl-specific tests (the ones that are in m4/curl-*.m4 files);
# - (most obvious thing:) curl version numbers.
# Add documentation subproject
#
# To check:
# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.
# Note: By default this CMake build script detects the version of some
# dependencies using `check_symbol_exists`. Those checks do not work
# in the case that both CURL and its dependency are included as
# sub-projects in a larger build using `FetchContent`. To support
# that case, additional variables may be defined by the parent
# project, ideally in the "extra" find package redirect file:
# https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package
#
# The following variables are available:
# HAVE_RAND_EGD: `RAND_egd` present in OpenSSL
# HAVE_BORINGSSL: OpenSSL is BoringSSL
# HAVE_PK11_CREATEMANAGEDGENERICOBJECTL: `PK11_CreateManagedGenericObject` present in NSS
# HAVE_SSL_CTX_SET_QUIC_METHOD: `SSL_CTX_set_quic_method` present in OpenSSL/wolfSSL
# HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in QUICHE
# HAVE_ZSTD_CREATEDSTREAM: `ZSTD_createDStream` present in Zstd
#
# For each of the above variables, if the variable is DEFINED (either
# to ON or OFF), the symbol detection will be skipped. If the
# variable is NOT DEFINED, the symbol detection will be performed.
